FREDERICK RINGROSE, OF HAMILTON, SCOTLAND.

AUTOMATIC LUBRICATOR.

Specification of Letters Patent.

Application filed May 14, 1910. Serial No. 561,412.

To all whom it may concern:

Be it known that I, FREDERICK RINGRosE, a subject of the King of the United Kingdom of Great Britain and Ireland, and residing at Hamilton, Scotland, have invented a certain new and useful Improvement in Automatic Lubricators, of which the following is a specification.

This invention relates to automatic lubricators and has for its object to provide an improved construction in which a pump or pumps is or are adapted to operate in con junction with stirring devices located within the vessel or vessels containing the lubricant, as hereinafter particularly described.

In the accompanying drawings Figures 1 and 2 are part elevations and part vertical sections at right angles to each other showing a lubricator constructed in accordance with the invention. Fig. 8 shows a modified arrangement of mixing devices hereinafter referred to.

Referring to the drawings, the lower part of the vessel A which contains the lubricant and which may be provided with a gage glass B is arranged to receive a stirring device for mixing graphite or the like which device may comprise a number of circular or other form of blades C attached to a spindle D having secured to it for example a ratchet wheel E or the like adapted to be rotated by a pawl F or the like on an arm G freely mounted on said spindle D and actuated in any suitable manner; or, as indicated in Fig. 3, said spindle D may be adapted to drive an endless chain H or the like located within said vessel A and having secured to it a number of blades I which serve to mix the graphite or the like.

As shown in Fig. 1, a lever D is secured to the spindle D so that the mixing devices can be operated manually if desired. A pump or pumps is or are adapted to be operated in conjunction with said mixing device to discharge the lubricant. Each pump may comprise two barrels J each communicating by means of a passage K with the vessel A and being connected to a chamber M fitted with non-return inlet and discharge valves O, P. Through each barrel J passes a plunger S connected to a yoke T operated by a cam or eccentric block U formed on or attached to a hollow sleeve V I surrounding the spindle D which drives the mixer. As shown, the plungers S enter externally screw-threaded portions t of the yoke T, which portions are slotted at-L to receive pins Q, on the plungers and are provided with spring nuts L adapted to engage said pins. By adjusting said nuts L in relation to said pins the stroke of the plungers may be varied or the pumps put out of action. The said hollow sleeve V has attached to it a ratchet wheel WV adapted to be operated for example by a pawl X carried by the arm G. A loosely mounted regulating shoe Y, capable of being secured in any desired position as by tightening a thumb screw Z or the like which engages a lower split portion 2 of theshoe, is adapted to extend circumferentially over the teeth of the pump ratchet wheel W whereby the speed of said pump is regulated on account of the driving pawl X riding over said shoe Y and taking an increased or diminished number of teeth at each stroke according to the position of said shoe.

Patented Nov. 29, 1910.

The chambers M of each pump have each a bran-ch pipe m connected to a delivery pipe N provided with a stop cock at, the branches m being adapted to communicate with one another through the intermediary of a cross branch N provided with a stop cock 11. the arrangement being such that the oil from each chamber N may be discharged through its corresponding delivery pipe N, or the oil from both discharge chambers M may be delivered through one delivery pipe N when the cook a of the other delivery pipe is closed and the stop cock n located on said cross branch N is opened. The plug of the cock n on each delivery pipe N may be provided with a port 77. adapted to communicate with a pipe connection a for returning the oil to the supply vessel A when desired, and each of said delivery pipes N may be adapted to serve as a sight feed or a separate sight feed may be fitted thereto.

Having now described my invention what I claim and desire to secure by Letters Patent of the United States is An automatic lubricator comprising in combination a vessel for containing lubricant, means for pumping said lubricant from I said vessel, stirrin means located within said vessel, devlces for operating said pumpin'g means, and devices for operating "said I name to this specification in the preseii'o'e of stirring means, said devices being adapted 11:0 tWo subscribing Witnesses. be operated simultaneously or independent y 7 V Q of one another and being arranged coaxially FRED RINGROSE 5 in relation to one another, substantially as described.

In testimony whereof I have signed my Witnesses:
